Parametric Triangular Plane Stress FEMs

This model is description parametric triangular plane stress finite element model.The element has constant thickness "th" and other dimensions depend the node cartesian coordinates.

Each of the per corners is assumed to posses two degress of freedom displacements "u" and "v" in the "x" and "y" directions,respectively.
Thus this element possesses has nodal forces (force pairs of Fx and Fy) and total nodal displacements or nodal degrees of freedom (node*2 pairs of u and v).Also ,in the finite element as select formulation method ,an important step is to assume the pertinent displacement interpolation functions ,usually of lineer degree polynomial format.

This models, zip files components is partial parametric and fullparametric models. Also parametric models had neglected isoparametric f.e.m. for smilarly boundary conditions.
